The metal housing (MGw) was developed as early as 2002 as a mast cabinet and is available with and without climate control. The cabinet is robust and durable (IP65) and tested for serial installation in signalling systems of an electronic interlocking. With its compact dimensions and the various installation options (socket, mast, tubular mast, concrete pylon or wall-mounted), it offers numerous possibilities to be applied in security-related (radio) signalling systems.

Various metal housings of steel have been used for many years e.g. as distributor on platforms or stations in Austria and other European countries. The outdoor cabinet offers the highest level of resistance against vandalism and external influences (graffiti, road salt, extreme weather) and is designed for locations with heavy public traffic, such as on stations or flag stops.
